Across
- 3. Law of Motion: an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force
- 5. Distance an object travels per unit of time
- 6. Isaac Newton English scientist, he studied and simplified the work of earlier scientists. He identified four laws that explained how the physical world works.
- 8. force Equal forces acting on an object in opposite directions
- 9. Force x Distance
- 10. A force that opposes the motion of objects that touch as they move past each other
- 12. A force of attraction between objects that is due to their masses.
- 15. force the cause of an object to start moving, stop moving or change direction
- 16. A change in position over time
Down
- 1. Unit for force
- 2. Rate at which velocity changes
- 4. Law of Motion: for every action there is an equal and opposite reaction
- 7. Speed in a given direction
- 10. A push or a pull
- 11. force The sum of all forces acting on an object.
- 13. Resistance to change in motion
- 14. Law of Motion: an object with an unbalanced force acting on it will accelerate in the direction of that force...f=m(a) ; force = mass times acceleration
